about how much hp can a sti turbo put out. like how much can it handle an how much could it put to the wheels if slapped onto a wrx 2.0 motor? how much psi could i push with just the sti turbo on my wrx?? an would i need to upgrade my fuel pump an injectors?

 

anyone?

 

Yeah, you'll need a new fuel pump, injectors and a reflash (ECUtek or AccessPort) to deal with the bigger turbo. I think you can safely push 18-20 (maybe more) psi though that turbo on the STi block, so I assume the same for the WRX.

Power to the wheels... I'll make a totally uneducated guess of 240hp/220wtq to the wheels

 

It would be similar to a VF34, so your guess is a bit low nKoan. With a catless uppipe, full 3" exhaust, supporting fuel mods and proper tune, probably 250-280 whp depending on whose dyno you choose to believe.

 

well i plan on running a full 3"inch catback exhaust, dp an im plannin on gett a walboro fuel pump an either sti injectors or a step up from that. . . but i know the wrx block is a open deck so it isnt as strong as the sti semi closed deck. . i was thinkin bout on the lines of like 280 to wheels like you said or lil less. . but couldnt i send my stock ecu off an get it reflashed an it work just as well?? thanks for the info
